There is no single solution to reduce or eradicate global poverty. And the solution to poverty will also be different in diverse countries. My children told me how poor Syria has become and I read that about 90% of Syrian citizens are living in poverty.  And I told them that the major reason for the poverty of that nations is war. So the solution to the poverty of Syria is the end of the war. So many nations in Africa are rich in mineral resources yet the poorest nations come from the continent.  It has been verified the major reason for poverty in Africa is corruption. Hence,  if you end corruption,  poverty in Africa might reduce to a great extent. Other nations are moving towards poverty because of natural disasters such as drought, flood,  earthquake, and others. Their only solution is to seek means to reduce these natural occurrences.  

As individuals, we have to seek alternative means of income if our earnings are not enough to satisfy our needs. You could also consider learning additional skills that can attract new opportunities to get more money. Reducing your expenses and channeling savings to viable investments will also help in reducing poverty.
